Former Japanese government advisor professor Takatoshi Ito said the agreement could benefit both countries.

"Basically it's a win-win situation that Australia can increase exports in those minerals, beef, and education, and the Japanese side will win in terms of exporting manufactured goods," he said.

Chair of the Australian and New Zealand Chamber of Commerce in Japan, Melanie Brock, says Mr Abbott has indicated he wants to conclude the agreement.

"How he uses the car tariff to gain further reduction in the beef tariff for us is a fine thing," she said.

"It's a balance of course because it's a negotiation. It will all come down to last minute, late night discussions I think.

"It toughens up our industries, it gives them more commercial access, it gives them a greater buy into the Japanese market, which is after all an extremely sophisticated, high quality, diverse market as well."
